NINDOV -SCREEN.

To all whom it may concern.

Be it known that I, JAMEs L. GILL, a citizen of the United States ofAmerica, residing at Bridgeton, in the county of Cumberland and State ofNew Jersey, have invented new and useful Improvements in Window-Screens, of which the following is a speci fication.

This invention relates to window screens, and particularly to that classin which a ortionof the frame thereof is adjustable and adapted tocontract and expand, to conform to varying widths of window frames, aswell as to readily, and removably secure the screen in place within thegrooves in which the window sashes slide.

Another object is to provide a resilient means for removably securingeither or both of the adjustable portions of the screen frame incontracted position.

Further advantages of the invention are fully brought out in thefollowing specification, when read in conjunction with the accompanyingdrawing, in which Figure 1 is a in its preferred form; Fig. 2 is asectional view on the line 2-2 of the Fig. l; and Fig. 3 is a sectionalview on the line 3-3 of Fig. 1.

Referring to the drawings, a window screen frame is shown as comprisingupper and lower sections 1 and 2, end sections 3 and a woven wire gauze4. The sections 3 are narrowed, as shown in Fig. 3, and cooperate withseparate, relatively movable sections 5, having an extension 6, adaptedto slide uponthe adjacent sections 3 as the positions of the former areshifted with respect thereto, to prevent flies or other insects frompassing therebetween.

Between the adjacent sections 3 and 5 and tending to press the sameapart are resilient members 7 preferably secured to the former andfrictionally engaging the latter. On

the other hand, to prevent a total separation of said sections, pins 8,having angularly bent portions 9, are secured to the adjustable sections5 and pass inwardly through apertures 10 in the sections 3, said bentportions being slidable in recesses 11 and normally inclosed by a plate12.

of the length ofthe Substantially midway sections 3 are apertures 15,through which bent; end

resilient pins 16, having reversely Copies of this patent may beobtained for Specification of Letters Patent.

Application filed March 20, 1914. Serial No. 826,063.

said sections are forced inwardly, the resiliency of said pins, afterthey are moved longitudinally inward, causes said portions 17 to snapupwardly into the position shown inFig. 1, wherein they cooperate withthe inner surface of the sections 3 to temporarily maintain thesect1ons'5 1n contracted position. From this posltion said last-namedsections will snap outwardly into engage:

ment with the window frame 20, upon pressing downwardly upon the bentportions 17, thus permitting the springs 7 to force the pins outwardlythrough the apertures 15.

In devices of this character, after moving 7 the adjustable sectionsinwardly before placing the screen in the window frame,

there is no means for temporarily retainingthem in such position andfrom which they can be readily released. lhis device par ticularlyprovides such a device, however, may be altered in its details ofconstruction and operation, and yet fall within the spirit of thepresent invention as well as within I claim: a

A window screen comprising a frame, the end rails of which are narrowerthan the top and bottom rails thereof, a wire mesh fabric supported bythe frame, the said end rails being formed with slots, leaf springsfixed in spaced relation to each other at the outer edges of the endrails of the frame, extensiwhich,
